Description
Die Erfindung betrifft eine Wundauflage zur Anwendung bei der Antiseptik von Kathetereintrittsstellen. Die Wundauflage umfasst eine transparente Folie und, auf die Folie aufgebracht, ein transparentes Hydrogel, das Octenidindihydrochlorid enthält. Sie betrifft ferner ein Wundauflage-Set und ein Octenidindihydrochlorid enthaltendes Hydrogel zur Verwendung für die Antiseptik von Kathetereintrittsstellen.The invention relates to a wound dressing for use in the antiseptic of catheter entry sites. The wound dressing comprises a transparent film and, applied to the film, a transparent hydrogel containing octenidine dihydrochloride. It further relates to a wound dressing set and an octenidine dihydrochloride-containing hydrogel for use in antiseptics of catheter entry sites.
Zur Verhinderung von katheterassoziierten Infektionen ist es derzeit üblich, die Haut vor dem Legen eines Katheters zu desinfizieren und damit zu pflegen, den Katheter zu legen und die Kathetereintrittsstelle danach mit einem üblichen Wundverband abzudecken. Alternativ kann die Einstichstelle mit einer Wundauflage abgedeckt werden, welche antimikrobiell ausgestattet ist. Ein Beispiel für eine antimikrobiell ausgerüsteter Wundauflage ist das Handelsprodukt biopatch®, das von der Firma Johnson & Johnson angeboten wird und als antimikrobiellen Wirkstoff Chlorhexidingluconat enthält. Eine andere bekannte Wundauflage ist das mit Silber antimikrobiell ausgerüstete Produkt SilvaSorb Site® der Firma Medline.To prevent catheter-associated infections, it is currently the practice to sanitize and condition the skin prior to laying a catheter, place the catheter and then cover the catheter entry site with a standard wound dressing. Alternatively, the puncture site can be covered with a wound dressing, which is equipped antimicrobial. An example of an antimicrobially modified wound dressing is the commercial product Biopatch ®, which is available from Johnson & Johnson and contains as antimicrobial agent chlorhexidine gluconate. Another known wound dressing is equipped with antimicrobial silver product SilvaSorb Site ® from Medline.
Es hat sich jedoch herausgestellt, dass sich Kathetereintrittsstellen bei Einsatz eines Wundverbands und auch bei Einsatz einer Wundauflage wegen der Undurchsichtigkeit des Trägermaterials schlecht optisch beurteilen lassen und deshalb die Gefahr besteht, dass eine verschleppte, weil unbeachtete Entzündungen auftritt. Hinzu kommt die hohe Rate an Unverträglichkeitsreaktionen bei Einsatz von Chlorhexidingluconat (insbesondere bei empfindlichen Patienten, wie z. B. immungeschwächten Patienten, onkologischen Patienten) oder Silber als Wirkstoff. Außerdem müssen die genannten Wundauflagen mit einem zusätzlichen (Klebe)-Verband oder einer Folie abgedeckt werden, um eine weitestgehende Keimfreiheit der Kathetereintrittsstelle zu gewährleisten. Hinzu kommt bei beiden beschriebenen Verfahren des Standes der Technik eine unzureichende antimikrobielle Wirkung über einen längeren Zeitraum, was ein unerwünscht häufiges Wechseln der Wundauflage/des Wundverbands notwendig macht, um eine Infektion sicher ausschließen zu können. Mit einem solchen Wechsel ist immer die Gefahr einer Neuinfektionen der Kathetereintrittsstelle verbunden.However, it has been found that, when using a wound dressing and also when using a wound dressing, because of the opacity of the carrier material, catheter entry points are poorly optically assessable and therefore there is a risk that an aborted, because unnoticed, inflammation occurs. In addition, the high rate of intolerance reactions when using chlorhexidine gluconate (especially in sensitive patients, such as immunocompromised patients, oncological patients) or silver as an active ingredient. In addition, the wound dressings mentioned must be covered with an additional (adhesive) band or a film in order to ensure the greatest possible sterility of the catheter entry site. In addition, in both described methods of the prior art, an insufficient antimicrobial effect over a longer period of time, which makes an undesirable frequent change of the wound dressing / wound dressing necessary to be able to exclude an infection safely. With such a change, the risk of a new infection of the catheter entry point is always connected.
Wegen dieser Nachteile ist eine Infektionen vermeidende Versorgung von Kathetereintrittsstellen bisher nicht zufriedenstellend möglich.Because of these disadvantages, an infection-avoiding supply of catheter entry sites has not been satisfactorily possible.
Der vorliegenden Erfindung hat deshalb die Aufgabe zu Grunde gelegen, Mittel zur Verhinderung von katheterassoziierten Infektionen bereitzustellen, mit deren Hilfe die beschriebenen Probleme des Standes der Technik vermieden werden können.The present invention is therefore based on the object of providing means for preventing catheter-associated infections, with the aid of which the described problems of the prior art can be avoided.
Es wurde nun überraschend gefunden, dass diese Aufgabe durch eine Wundauflage gelöst wird, die umfasst:
- a) eine transparente Folie und
- b) auf die Folie aufgebracht ein transparentes Hydrogel, das Octenidindihydrochlorid enthält.
- a) a transparent film and
- b) applied to the film a transparent hydrogel containing octenidine dihydrochloride.
Die Erfindung beruht unter anderem darauf, dass gefunden wurde, dass Hydrogele den antimikrobiellen Wirkstoff Octenidindihydrochlorid nicht nur schnell, sondern überraschenderweise auch lang anhaltend freisetzen. Dadurch werden die Unverträglichkeitsreaktionen vermieden, die mit Chlorhexidingluconat oder Silber als Wirkstoff beobachtet werden. Ferner werden Infektionen zuverlässig und langanhaltend verhindert. Somit lässt sich im Bereich der Hautantiseptik an einer Einstichstelle z. B. eine gesteigerte Leistungsfähigkeit sowie eine Steigerung der Sicherheit im Vergleich mit der üblichen Hautantiseptik herbeiführen. Außerdem erlauben die transparente Folie und das transparente Hydrogel eine gute Überwachung der Kathetereintrittsstelle, wodurch eine verschleppte, weil unbeachtete Entzündung derselben vermieden werden kann, ohne dass zur Kontrolle ein häufiger Wechsel der Wundauflage notwendig ist.The invention is based inter alia on the finding that hydrogels release the antimicrobial active ingredient octenidine dihydrochloride not only rapidly, but also surprisingly long-lasting. This avoids the incompatibility reactions observed with chlorhexidine gluconate or silver as the active ingredient. Furthermore, infections are prevented reliably and long-lasting. Thus, in the area of skin antisepsis at a puncture site z. B. bring about increased performance and an increase in safety compared to the usual skin antisepsics. In addition, the transparent film and the transparent hydrogel allow a good monitoring of the catheter entry point, whereby a delayed, because unnoticed inflammation thereof can be avoided without the need for frequent control change of the wound dressing is necessary.
I. WundauflageI. wound dressing
a) Foliea) foil
Die erfindungsgemäße Wundauflage weist eine transparente Folie auf. Die Folie muss nicht vollständig transparent sein. Es reicht beispielsweise aus, wenn der bei der späteren Anwendung die Kathetereintrittsstelle bedeckende Teil der Folie transparent ist. Die Wundauflage ist jedoch vorzugsweise nicht nur in dem Bereich, der das Hydrogel aufweist, sondern auch in dem Klebebereich und insbesondere auf der ganzen Fläche transparent.The wound dressing according to the invention has a transparent film. The foil does not have to be completely transparent. It is sufficient, for example, if the part of the film which covers the catheter entry point during subsequent use is transparent. However, the wound dressing is preferably not only in the Area that has the hydrogel, but also in the gluing area and especially on the entire surface transparent.
Die Transparenz bzw. Lichtdurchlässigkeit wird in Anlehnung an
Die erfindungsgemäß eingesetzte Folie kann einschichtig oder mehrschichtig ausgebildet sein, ist jedoch vorzugsweise einschichtig ausgebildet. Dabei sind in. allen Ausführungsformen der Erfindung rechteckige Folien bevorzugt. Typische Maße der Folie sind etwa 3 × etwa 3 cm. Alternativ ist es möglich, die erfindungsgemäßen Folien rund auszubilden, vorzugsweise beträgt der Durchmesser dann etwa 3 cm.The film used in accordance with the invention may be single-layered or multi-layered, but is preferably single-layered. In this case, in all embodiments of the invention rectangular films are preferred. Typical dimensions of the film are about 3 × about 3 cm. Alternatively, it is possible to form the films of the invention around, preferably, the diameter is then about 3 cm.
Eine typische Dicke der erfindungsgemäß eingesetzten Folie beträgt 5–500 μm, vorzugsweise 50–200 μm.A typical thickness of the film used according to the invention is 5-500 μm, preferably 50-200 μm.
Als Folienmaterial geeignet sind Polymerfilme, vorzugsweise mit atmungsaktiven Eigenschaften, z. B. Polyester- oder Polyether-Polyurethane (wie z. B. ESTANE®, B.F. Goodridge), Polyether-Polyamide (wie z. B. PEBAX®, Arkema), aber auch hydrophile und hydrophobe Polyurethane bzw. solche mit elastomeren Eigenschaften (wie z. B. HYTREL®, DuPont).Suitable film materials are polymer films, preferably with breathable properties, for. For example, polyester or polyether polyurethanes (such as ESTANE ® , BF Goodridge), polyether polyamides (such as PEBAX ® , Arkema), but also hydrophilic and hydrophobic polyurethanes or those with elastomeric properties (such z. B. HYTREL ®, DuPont).
Die Folie besitzt vorzugsweise eine besonders gute Wasserdampfdurchlässigkeit von > 500 g/m2/24 h, insbesondere aber von > 2500 g/m2/24 h. Die Wasserdampfdurchlässigkeit wird gemäß
Dabei ist eine Ausführungsform möglich, bei der die Folie der Wundauflage in einem Bereich mit einem Klebstoff beschichtet ist, beispielsweise auf der Basis von Poly(meth)acrylat, und in einem anderen Bereich mit dem Hydrogel versehen ist. Der mit dem Hydrogel ausgerüstete Bereich macht vorzugsweise 5 bis 95%, vorzugsweise 50 bis 80%, wie etwa 70% der Gesamtfläche der Wundauflage aus.In this case, an embodiment is possible in which the film of the wound dressing is coated in one area with an adhesive, for example on the basis of poly (meth) acrylate, and provided in another area with the hydrogel. The area provided with the hydrogel preferably accounts for 5 to 95%, preferably 50 to 80%, such as about 70% of the total area of the wound dressing.
Die erfindungsgemäße Wundauflage weist besonders bevorzugt auf der Seite der Folie, die das Hydrogel aufweist, eine Abziehfolie auf. Derartige Abziehfolien sind aus dem Stand der Technik bekannt. Beispielsweise werden Abziehfolien aus Polyethylenterephthalat, Polyethylen, Polypropylen oder Polyvinylchlorid eingesetzt. Somit ergibt sich in den Bereichen der Wundauflage, die das Hydrogel aufweisen, eine Schichtenfolge Folie – Hydrogel – Abziehfolie, und in den Bereichen, die kein Hydrogel aufweisen, eine Schichtenfolge Folie – Abziehfolie.The wound dressing according to the invention particularly preferably has a peel-off film on the side of the film which has the hydrogel. Such release liners are known from the prior art. For example, release liners of polyethylene terephthalate, polyethylene, polypropylene or polyvinyl chloride are used. Thus, in the regions of the wound dressing which comprise the hydrogel, there is a layer sequence of film hydrogel release film, and in the regions which have no hydrogel, a layer sequence of film release film.

Bioverfügbarkeit von Octenidindihydrochlorid in einem HydrogelBioavailability of octenidine dihydrochloride in a hydrogel
Die Bioverfügbarkeit von Octenidindihydrochlorid aus einem Hydrogel wurde mittels des Sartorius Liberationsmodells (Typ SM 16755) geprüft.The bioavailability of octenidine dihydrochloride from a hydrogel was tested by the Sartorius Liberations model (type SM 16755).
Die Salbenliberationszelle besteht aus drei durch Bolzen und Muttern zusammengehaltenen durchsichtigen Plexiglasplatten. In zwei Platten sind Kammern eingelassen. Der Temperierraum in der mittleren Platte wird mit Temperierwasser durchströmt. In der gleichen Platte befindet sich gegenüber dem Temperierraum die Salbenkammer zur Aufnahme der zu untersuchenden Substanz. In der Platte durchströmt das Akzeptormedium die Riffelplatte, wo es in Kontakt mit der Membran den freigesetzten Wirkstoff aufnimmt.The ointment liberalization cell consists of three transparent plexiglass plates held together by bolts and nuts. In two plates chambers are embedded. The tempering in the middle plate is traversed by tempering. In the same plate is opposite the tempering the ointment chamber for receiving the substance to be examined. In the plate, the acceptor medium flows through the corrugated plate, where it receives the released drug in contact with the membrane.
Temperatur- und Akzeptormedium besitzen somit zwei unabhängige Kreisläufe. Aus der Kammer des Akzeptormediums wird die Probe zur Gehaltsbestimmung gezogen.
Prüfprodukt: Hydrogel I
Photometermethode: Photometer Cadas 100, Fa. Dr. Lange (280 nm)Temperature and acceptor medium thus have two independent circuits. From the chamber of the acceptor medium, the sample is drawn for content determination.

Zunächst wird eine Kalibrierung für den Wirkstoff Octenidindihydrochlorid durchgeführt.First, a calibration for the active ingredient octenidine dihydrochloride is performed.
Das Prüfprodukt wird in die Salbenkammer eingewogen. Zu den genannten Zeitpunkten werden Proben entnommen. Das entnommene Probevolumen wird vollständig durch neues Akzeptormedium ersetzt. Nach Ende der Gesamtlaufzeit werden die Proben bei 280 nm in 1 cm Quarzküvetten vermessen.The test product is weighed into the ointment chamber. Samples are taken at the stated times. The sample volume removed is completely replaced by new acceptor medium. After the end of the total run time, the samples are measured at 280 nm in 1 cm quartz cuvettes.
Die Ergebnisse sind in der folgenden Tabelle wiedergegeben:
Die Ergebnisse zeigen, dass eine gute und kontinuierliche Freisetzung des Wirkstoffes Octenidindihydrochlorid aus dem Hydrogel erfolgt. Nach 24 Stunden sind 90% des enthaltenen Wirkstoffs aus dem Gel freigesetzt.The results show that a good and continuous release of the active ingredient octenidine dihydrochloride from the hydrogel takes place. After 24 hours, 90% of the active substance contained is released from the gel.
